Definitions

  • the present invention relates generally to a carton for carrying a number of articles or containers which can be opened and some of the articles or containers removed and the carton reduced in size and reclosed.
  • This process of removing articles or containers and reducing the carton in size and reclosing can be done two or three times or more if desired.
  • This reduction in size is accomplished by providing a set of tear and fold lines for each reduction in size to allow part of the carton to be removed and discarded and to form a new reclosable top for the carton for the reduced size.
  • Cartons that carry a number of articles or containers are frequently opened one or more times and one or more articles or containers removed and the carton reclosed.
  • the present invention relates to a carton that can be reopened and incrementally reduced in size and reclosed. This carton has two main main
  • the carton has two ends with one end being an opening end that can be closed by two main end flaps. The other end of the carton may be closed in the same manner or with another type of closing means.
  • This carton can be folded into a sleeve and glued together and loaded with articles or containers. The ends of the carton can then be closed and preferably glued together.
  • the opening end of the carton can be opened and articles removed from the carton.
  • the carton can then be incrementally reduced in size by pushing in and pulling a tab in the first closing flap in a main panel and removing the attached main end flap from the carton.
  • Tear lines are provided in each side panel that extend downwardly from the open end of the carton near each side of the first closing flap to the fold line between each side panel and the opposite main panel. These diagonal side tear lines are connected to a first main tear line in the opposite main panel. The tearing of these side tear lines and first main tear line results in the removal of a portion of each side panel and the incremental opposite main panel.
  • the other part of the first incremental section of the carton can then be folded into a reclosable top by folding the first closing flap and the first top panel about fold lines.
  • a gusset fold line may extend from the center of each side tear line to the intersection of the main panel and the first closing fold line. Pushing in the gusset panels formed by the gusset fold lines allows the first closing flap and first top panel to be easily folded and reclosed. This process can be continued for a second additional incremental reduction in the carton and reclosing the carton. The second increment results in alternating the various tear and fold lines so that the second top panel and second closing flap are located in the opposite main panel and the second main tear line is in the main panel. This process can be continued for a third additional incremental reduction in the carton and reclosing the carton.
  • the third increment results in again alternating the various tear and fold lines so that the third top panel and third closing flap are located in the main panel and the third main tear line is in the opposite main panel.
  • additional incremental reductions may be made.
  • the tab that is used for removing the main end flap may have an arcuate tear line connecting it to the first closing flap. This tab may be used on each subsequent increment.
  • the first end fold line and other end fold lines can be extended into each side panel to form another gusset panel to further ease the reclosing of the top.
  • FIG. 1 is a plan view of the blank for forming one embodiment of a carton of this invention.
  • FIG. 2 is a perspective view of a carton formed from the blank of FIG. 1 which has been loaded with product, closed and sealed.
  • FIG. 3 is a perspective view of the loaded carton of FIG. 2 which has been opened and some articles or containers removed from the carton and the first removable incremental section near the opening end of the carton torn away from the carton.
  • FIG. 1 is a plan view of the blank for forming one embodiment of a carton of this invention.
  • FIG. 2 is a perspective view of a carton formed from the blank of FIG. 1 which has been loaded with product, closed and sealed.
  • FIG. 3 is a perspective view of the loaded carton of FIG. 2 which has been opened and some articles or containers removed from the carton and the first removable incremental section near the opening end of the carton torn away from the carton.
  • FIG. 4 is a perspective view of the carton of FIG. 3 in which the first reclosable top has been folded and closed.
  • FIG. 5 is a perspective view of the carton of FIG. 4 which has been reopened and product removed and the second removable incremental section torn away from the opening end of the carton.
  • FIG. 6 is a perspective view of the carton of FIG. 5 in which the second reclosable top has been folded and closed.
  • FIG. 7 is a perspective view of the carton of FIG. 6 which has been reopened and product removed and the third removable incremental section tom from the opening end of the carton.
  • FIG. 8 is a perspective view of the carton of FIG. 7 in which the third reclosable top has been folded and reclosed.
  • the present invention is primarily for use with articles or containers which are removed from the carton one or two at a time and the carton reclosed.
  • the carton of this invention is especially useful for products that are stored in the refrigerator or freezer and taken out of the carton which' is restored with the remaining contents. Products such as toasted pastries, spring rolls and meat pies are typical of the products that are removed from a carton and the carton reclosed and restored either in the
  • the blank 10 for forming the carton of this invention is formed from a foldably sheet of material, such as paperboard.
  • the carton of this invention has the main panel 11 and an opposite main panel 13. In viewing the main panel 11, a main end flap 12 is foldably attached to first closing flap 14 by fold line 18.
  • a cut or tear line 16 is provided in lieu of a fold line along much of the border between the main end flap 12 in first closing flap 14.

  • the carton of this embodiment can be incrementally reduced in size three times and reclosed.
  • the incremental sections that need to be torn and folded and reclosed are illustrated by roman numerals I, II, and TJI in FIG. 1.
  • first side tear line 92A is located in side panel 72 and first tear line 92B is located in opposite side panel 74.
  • incremental section I may have first gusset fold lines 94A in side panel 72 and 94B in opposite side panel 74.
  • first side tear lines 92A-B and first gusset fold lines 94A- B result in the forming gusset panels G.

  • This carton can be reclosed in the conventional manner by reclosing side end flaps 84 and 86 and main end flaps 12 and 46. If desired, this carton can be reduced in size by the tearing and folding of incremental section I. This is accomplished by pushing in tab 19 resulting in the tearing of arcuate tear line 20 which results in the tearing of main end flap 12 from the carton.
  • first side tear lines 92A-B are extended across comers of first closing flap 14 to cut line 16. These comers are attached to main end flap 12 by a small portion of fold lines 50 and 108.

Now that the carton has been reduced in size, it can be easily reclosed by pushing in on first gusset fold lines
  • First end fold line 24 can be extended to first side tear lines 92A-B which also forms a small gusset panel G on one side of each fold line when pushed in. These gusset panels G can be pushed in without the use of first end fold line 24 extending to first side tear lines 92A-B. Rough gusset panels can be created without the presence of first gusset fold lines 94A-B, but these fold lines facilitate the reclosing of the first reclosable top.

While three incremental sections I, II and III are shown in this embodiment a fewer or larger number of incremental sections can be placed in a carton. It should also be realized that the incremental sections do not all have to be of the same size.
  • the reclosable carton of this invention is suitable for packaging articles or containers that are placed in a carton and removed one or more at a time.
  • the carton of this invention is especially useful for products that are stored in the refrigerator, freezer, or pantry where space is limited. This reclosable carton also helps to preserve the freshness of items contained in the carton. If a recipe or instmctions are to be included with a product that is contained in this carton, such as a food product that is to baked or heated, the recipe or instructions T can be repeated on each increment of the carton. For example, a main label with a recipe or heating instmctions could be repeated for the entire carton on each incremental segment.
  • the main label could be placed on incremental opposite main panel 48, first incremental main panel 26, second incremental opposite main panel 60 and third incremental main panel 38. This is possible with this embodiment because it is designed to have a large main panel each time a removable section is removed from the carton. It is preferable for appearance purposes to have the instmctions or recipe printed only once, which should be on the third incremental main panel 38 which will be present on each incremental carton since incremental section III is the mother pack.
  • the letter L as shown in FIG. 1 represents the border of the instmctions or recipe T as viewed from the inside of the blank.
  • One characteristic of this embodiment of the invention is that the side tear lines in each incremental section are parallel to each other when the blank has been formed into a carton.
  • first side tear lines 92A and 92B are parallel to each other. This facilitates tearing off the removable sections of each incremental section and producing a well defined reclosable top.
  • the closing fold line should be interconnected with the main tear line.
  • first closing fold line 28 should be interconnected with first main tear line 54.
  • the closing fold lines 28, 62, and 40 basically serve as hinges for closing top panels 22, 56, and 34 respectively when the reclosable top is being closed and opened.

Abstract

La présente invention concerne un carton qui peut être ouvert, réduit en taille par incrément et refermé. Une ligne de déchirure horizontale (16,32) est placée dans un panneau principal (11) de ce carton et connectée à une ligne de déchirure diagonale (92A, 92B, 96A, 96B) présente dans chaque panneau latéral (72,74), qui s'étend vers le haut et traverse vers l'autre panneau principal (13). Lorsque ces lignes de déchirure sont déchirées le carton voit sa taille réduite par cet incrément (I, II). Un couvercle refermable est formé dans un panneau principal par deux lignes de pliage (24, 28, 36, 40) qui s'étendent à travers ce panneau. Une ligne de pillage de soufflet (94A, 94B, 98A, 98B) dans chaque panneau latéral qui s'étend à partir de chaque ligne de déchirure vers le bas en direction d'un panneau principal permet au panneau supérieur et au volet de fermeture du carton d'être fermés. Ce carton peut posséder plusieurs parties qui peuvent être réduite en taille par incrément et refermées lorsque que des articles sont retirés de ce carton.
